Learn CompTIA A+

Learn the IT support fundamentals behind the CompTIA A+ certification.

Free to start. Built from a single prompt. No credit card.

CompTIA A+ is an entry-level IT certification for help desk and technical support roles. It requires passing two exams, Core 1 and Core 2. Core 1 covers hardware, mobile devices, networking, virtualization and cloud basics, plus hardware and network troubleshooting. Core 2 covers operating systems, security, software troubleshooting and operational procedures such as documentation and safety. Both include performance-based questions that simulate real tasks. Learnr is not affiliated with CompTIA; it builds a course that teaches the concepts behind each objective.

How to learn CompTIA A+, step by step

Download the official exam objectives. CompTIA publishes a detailed objectives list for each exam version. Use it as your checklist, because exam versions change and study materials for an older version may cover outdated topics.
Get hands-on with real hardware. Open an old desktop, identify the motherboard, RAM, storage and power supply, and reassemble it. Physical familiarity with connectors and form factors makes hardware questions far easier than memorizing pictures.
Learn the troubleshooting methodology. CompTIA tests a specific order: identify the problem, establish a theory, test it, plan and implement a fix, verify functionality, and document. Practice applying those steps to scenarios until the order is automatic.
Practice Windows tools and commands. Set up a virtual machine and use Task Manager, Event Viewer, Disk Management and commands such as ipconfig, ping and chkdsk. Performance-based questions expect you to know which tool solves which problem.
Memorize ports and protocols with spaced review. Common port numbers and protocols, such as HTTPS, SSH, RDP and DNS, appear repeatedly. Short daily quizzes, like Learnr lessons with streaks, are an efficient way to make them stick.
Take full practice exams for each core. Use reputable practice exams aligned with the current objectives and time yourself. Review every wrong answer against the objective it maps to, and revisit that domain before testing again.

What you'll learn

Identify PC components, ports, cables and connectors
Explain basic networking, including IP addressing, DNS and Wi-Fi standards
Configure and troubleshoot Windows using common tools and commands
Apply security basics such as malware removal and account management
Follow a structured troubleshooting methodology for hardware and software

How long does it take to learn CompTIA A+?

With no IT background, many people prepare for both exams over 3 to 6 months at 5 to 10 hours a week. Hands-on experience with computers or support work can shorten that considerably.

What you need before you start

No formal prerequisite. Basic computer literacy is enough to begin, and access to an old PC or a virtual machine helps a great deal.

Common mistakes to avoid

Studying from materials for an older exam version. Check the exam code on CompTIA's site and match your resources to the current objectives.
Memorizing facts without hands-on practice. Performance-based questions simulate real tasks, so practice in a virtual machine or on real hardware.
Skipping the troubleshooting steps order. Scenario questions often hinge on what to do next, such as documenting findings at the end.

CompTIA A+ questions, answered

Do I need to pass both A+ exams?

Yes. A+ certification requires passing both Core 1 and Core 2. You can take them in either order. Check CompTIA's site for current exam codes, pricing and retirement dates.

Is A+ worth it with no experience?

A+ is designed as an entry-level credential for support roles and is often listed in help desk job postings. Pairing it with hands-on practice and projects makes it more useful.
